This week in Flutter #69: Flutter (3.3) Vikings

What a week for Flutter. The (biggest?) Flutter conference && a new Flutter version. Did you miss Flutter Vikings? Here is a pre-conference article with the most interesting talks, selected by Taha Tesser.

Olivier Revial published a summary of the talks he managed to attend for day 1 and day 2. You can also watch all the talks on Youtube. I am going to do it in the next two weeks.

During the conference, the Flutter team announced Dart 2.18 and Flutter 3.3 part1 and part 2.

On the Dart side, Objective-C & Swift interoperability is in preview, and it is already used in third-party plugins, like Native Dio Client by Jonas Uekötter. Type inference for generic functions is also improved, and I am looking forward to experiencing it in my IDE. Finally, the Dart team announced that non-null safety and unsound null safety will not be supported from next year. Time to update that app you did not touch in 2 years.

Many more updates for Flutter. My favorite is Impeller, the next-generation rendering layer. It is not fully available yet, but it is very promising.

Let me know what you think of these updates.

“A widget representing a physical layer that clips its children to a shape.” No idea what this means? Then watch the video.

That’s it for this week.
